Answer:

x = 1/3

Step-by-step explanation:

3x-1=6x-2

3x-1+1=6x-2+1

3x=6x-1

3x-6x=6x-1-6x

-3x=-1

x=1/3

In a fruit punch drink, the 3 ingredients are apple juice, orange juice and cranberry juice. If 3/4 of the drink is apple juice

SVETLANKA909090 [29]

Step-by-step explanation:

Let's assume x = apple juice, y = orange juice, and z = cranberry juice

$1 = x + y + z \\ 1 = \frac{3}{4} + \frac{1}{10} + z \\ z = 1 - \frac{3}{4} - \frac{1}{10} \\ z = \frac{3}{20}$

<u>x : y : z = 3/4 : 1/10 : 3/20</u>

If we were to make them all in the same denominator, x : y : z = 15/20 : 2/20 : 3/20.

$\frac{3}{4} \times \frac{5}{5} = \frac{15}{20} \\ \\ \frac{1}{10} \times \frac{2}{2} = \frac{2}{20}$

How do you simplify <img src="https://tex.z-dn.net/?f=7%5Csqrt%5B4%5D%7B80pq%5E%7B2%7Dr%5E%7B8%7D%20%20%7D" id="TexFormula1" tit

Answer:

$14 ( 5)^{\frac{1}{4}} p^{\frac{1}{4}} q^{\frac{1}{2}} r^{2}$

Step-by-step explanation:

The expression to simplify in this problem is

$7\sqrt[4]{80pq^2r^8}$

Which can be rewritten as

$7(80pq^2r^8)^{\frac{1}{4}}$

Or also as

$7\cdot 80^{\frac{1}{4}} \cdot p^{\frac{1}{4}} \cdot (q^2)^{\frac{1}{4}} \cdot (r^8)^{\frac{1}{4}}$

Now we can apply the following rule for the calculation of the power of a power:

$(a^m)^n = a^{m\cdot n}$

So we get:

$7\cdot 80^{\frac{1}{4}} \cdot p^{\frac{1}{4}} \cdot q^{\frac{1}{2}} \cdot r^{2}$

Which can therefore be rewritten as

$7\cdot (2^4\cdot 5)^{\frac{1}{4}} \cdot p^{\frac{1}{4}} \cdot q^{\frac{1}{2}} \cdot r^{2}$

And so, we get

$7\cdot 2 \cdot ( 5)^{\frac{1}{4}} \cdot p^{\frac{1}{4}} \cdot q^{\frac{1}{2}} \cdot r^{2}$

which can be finally rewritten as

$14 ( 5)^{\frac{1}{4}} p^{\frac{1}{4}} q^{\frac{1}{2}} r^{2}$

This baseball season, Barry gets two hits for every 16 at bats. This statement represents his batting average.

Katen [24]

Answer:

A. 1/8 or 0.125

B. No

Step-by-step explanation:

A. The batting average formula is: (# of hits) ÷ (# of at-bats).

Here, we see that Barry has 2 hits and 16 at-bats, so plug these numbers into the formula:

(# of hits) ÷ (# of at-bats)

2 ÷ 16 = 1/8 = 0.125

B. Batting average is always rounded to the thousandths place; in other words, we only calculate the number up to the third decimal place.

Looking at our batting average calculated in part A, it's 0.125, which is already at the third decimal place, and we can see that there is clearly no 0 at the end. So, the answer is no.
